Recreate the barplot below that shows the population of different continents for the year 2007.
Hints:
# YOUR CODE HERE
df_2007 = df.query("year==2007")
dx = df_2007.groupby('continent').sum()
fig = px.bar(dx, x="pop", y=dx.index, color = dx.index, orientation='h', text='pop')
fig.show()
# YOUR CODE HERE
fig.update_yaxes(categoryorder="sum ascending")
fig.show()
Add text to each bar that represents the population
# YOUR CODE HERE
fig.update_yaxes(categoryorder="sum ascending")
fig.update_traces(texttemplate='%{text:.2s}', textposition='inside')
Thus far we looked at data from one year (2007). Lets create an animation to see the population growth of the continents through the years
# YOUR CODE HERE
fig = px.bar(df, x='continent', y='pop', color='continent', animation_frame="year", animation_group='country',
range_y=[0, 4000000000])
fig.show()
Instead of the continents, lets look at individual countries. Create an animation that shows the population growth of the countries through the years
# YOUR CODE HERE
fig = px.bar(df, x='pop', y='country', color='country', animation_frame="year",
range_y=[0, 14000000],
orientation='h')
fig.update_yaxes(categoryorder="sum ascending")
fig.show()
Clean up the country animation. Set the height size of the figure to 1000 to have a better view of the animation
# YOUR CODE HERE
fig.update_layout(height=1000)
fig.update_yaxes(categoryorder="sum ascending")
fig.show()
# YOUR CODE HERE
fig = px.bar(df, x='country', y='pop', color='country', animation_frame="year",
range_y=[0, 1400000000],
range_x=[0, 9])
fig.update_xaxes(categoryorder="sum descending")
fig.show()
